The Verse of Purification ​

The Verse of Purification () holds a central place in Qur’anic exegesis due to its profound implications for understanding the role and purity of the Ahl al-Bayt—the People of the Household of the Holy Prophet (s.a.w.). The verse reads:

“And stay in your houses and do not flaunt your finery like the former (days of) ignorance, and maintain the prayer, give the charity, and obey God and His Apostle. God only desires to keep away impurity from you, O People of the Household, and to purify you thoroughly.”

In Tafsīr al-Mīzān, ʿAllāmah Ṭabāṭabāʾī provides a meticulous analysis of this verse, addressing its linguistic, theological, and narrational dimensions. His examination demonstrates that while the surrounding verses are directed at the Prophet’s wives, the phrase regarding purification specifically applies to a select group within the Prophet’s family. This interpretation highlights the unique status of the Ahl al-Bayt as divinely chosen figures entrusted with preserving the moral and spiritual integrity of Islam.

The preceding sections of the verse address the wives of the Prophet, outlining their responsibilities and the conduct expected of them. By stating, “O wives of the Prophet! You are not like any other women” (), the Qur’an acknowledges their unique status due to their proximity to the Prophet, yet emphasizes that this privilege alone does not automatically confer spiritual merit. Their excellence is tied to their piety and adherence to divine commands. The instructions given to the wives reflect their important role as models of virtue within the Muslim community. For example, the command “Be not soft in your speech, lest a man with a diseased heart desire (you)” () cautions against using tones that might evoke improper desires or suspicions among morally weak individuals. Instead, they are instructed to speak in a dignified and straightforward manner that aligns with Islamic principles of propriety. Furthermore, the exhortation to “stay in your homes and do not flaunt your charms as was done in the first Age of Ignorance” serves as a reminder to maintain modesty and avoid the practices of pre-Islamic Arabia, where women openly displayed their beauty in ways that undermined societal morality. The term qarna (“stay”) does not imply seclusion but rather emphasizes the importance of maintaining their roles as exemplars of modest conduct within the household.

At this point, the verse shifts in tone and pronoun usage with the statement: “God only desires to remove any impurity from you, O People of the Household, and to purify you thoroughly.” This segment, known as the Verse of Purification, marks a deliberate and significant transition. The shift from the feminine plural pronoun (ʿankunna) to the masculine plural pronoun (ʿankum) signals a change in audience. While the preceding and subsequent verses address the Prophet’s wives, the purification clause pertains to a distinct group—the Ahl al-Bayt (a.s.). This linguistic distinction is not coincidental but carries theological weight, as the masculine plural includes both men and women. Through careful analysis of both the Qur’an and supporting narrations, ʿAllāmah Ṭabāṭabāʾī identifies the members of the Ahl al-Bayt as the Prophet himself, ʿAlī, Fāṭimah, Ḥasan, and Ḥusayn (peace be upon them).

Various alternative interpretations are addressed and systematically refuted. Some commentators claim that the verse refers exclusively to the Prophet’s wives, arguing that the context of surrounding verses supports this interpretation. However, this claim is undermined by the grammatical inconsistency of using the masculine plural pronoun to address a group of women. Others propose that the Ahl al-Bayt (a.s.) includes both the wives and other relatives of the Prophet, such as the family of ʿAbbās, Jaʿfar, and ʿAqīl. This broader interpretation, however, lacks textual and narrational support. Authentic narrations repeatedly emphasize that the purification mentioned in the verse is exclusive to the Prophet, ʿAlī, Fāṭimah, Ḥasan, and Ḥusayn. These narrations, which are widely documented in both Sunni and Shia sources, provide a consistent and clear understanding of the verse. For instance, reports from Um Salamah, one of the Prophet’s wives, describe the well-known event of Hadīth al-Kisāʾ (the Tradition of the Cloak), where the Prophet gathered ʿAlī, Fāṭimah, Ḥasan, and Ḥusayn under a cloak and prayed for their purification. When Um Salamah sought inclusion in this group, the Prophet gently affirmed her virtuous position but clarified that the verse’s purification was specific to these five individuals.

The phrase “God only desires to remove any impurity from you, O People of the Household, and purify you thoroughly” is analyzed with particular attention to the meaning of rijs (impurity) and the nature of divine will (irādah). The term rijs here is not limited to physical impurity but encompasses all forms of spiritual and moral flaws. This complete purification signifies protection from sin and error, aligning with the concept of ʿiṣmah (infallibility). ʿAllāmah explains that the phrase “God only desires” refers to God’s creational will (irādah takwīniyyah), which denotes a definitive act of God that brings about a guaranteed reality. Unlike legislative will (irādah tashrīʿiyyah), which commands human beings to strive toward a goal, this divine will does not depend on human effort or compliance. God’s desire to purify the Ahl al-Bayt (a.s.) is thus an eternal and irrevocable act, ensuring their infallibility and moral perfection. This distinction becomes even clearer when contrasted with the earlier admonitions directed at the Prophet’s wives, where the expectation of piety reflects legislative will that requires effort and compliance. The shift in tone from legislative to creational will highlights the unique and divinely guaranteed purity of the Ahl al-Bayt.

ʿAllāmah also addresses the verse’s placement within the larger context of Chapter 33, which focuses on the conduct of the Prophet’s household. While the purification clause appears within a passage addressing the Prophet’s wives, narrations confirm that it was revealed independently. This pattern of insertion mirrors other instances in the Qur’an, where distinct revelations are embedded within broader contexts for thematic continuity. The independent nature of the Verse of Purification further strengthens the argument that it refers exclusively to the Ahl al-Bayt (a.s.).

Through this detailed analysis, ʿAllāmah concludes that the Verse of Purification affirms the divinely ordained purity of the Prophet, ʿAlī, Fāṭimah, Ḥasan, and Ḥusayn. This purification, as an act of God’s creational will, signifies their infallibility and establishes them as the foremost exemplars of moral and spiritual excellence. The Ahl al-Bayt, by virtue of this divine gift, are entrusted with the responsibility of preserving the integrity of Islam and guiding the Muslim community. The verse stands as both a declaration of their elevated status and a testament to their role as the guardians of the prophetic legacy. Through the profound insights in Tafsīr al-Mīzān, the significance of the Verse of Purification becomes clear: it highlights the unique relationship between divine will and the Ahl al-Bayt (a.s.), affirming their central position in the spiritual and moral framework of Islam.


  1. The Ahl al-Bayt is identified as the Prophet, ʿAlī, Fāṭimah, Ḥasan, and Ḥusayn. This identification is supported by Sunni and Shia traditions alike, with narrations from companions such as Umm Salamah, who confirmed the verse’s application exclusively to these five individuals. ↩︎

  2. The shift from the feminine plural pronoun (ʿankunna) to the masculine plural pronoun (ʿankum) marks a change in the addressed group. This change is significant as it cannot linguistically refer to the Prophet’s wives alone. The masculine plural includes both men and women, signaling a broader audience. Reference: Ibn Hajar al-ʿAsqalānī in Fath al-Bārī (vol. 7) and Zamakhsharī in al-Kashshāf both recognize the pronoun shift as indicative of a specific distinction within the Prophet’s household. ↩︎

  3. References: Various narrations in al-Durr al-Manthūr, Ghāyat al-Marām. ↩︎

  4. The Hadīth al-Kisāʾ is a widely accepted narration that contextualizes the Verse of Purification. The Prophet (s.a.w.) gathered ʿAlī, Fāṭimah, Ḥasan, and Ḥusayn under a cloak and prayed, “O God, these are the People of my Household; remove impurity from them and purify them thoroughly.” (al-Durr al-Manthūr, Ghāyat al-Marām) ↩︎

  5. The term rijs in this verse extends beyond physical impurity to encompass moral and spiritual defects. The interpretation of rijs as referring to spiritual and moral purity is consistent across classical exegeses. Reference: Fakhr al-Dīn al-Rāzī in al-Tafsīr al-Kabīr emphasizes the broader meaning of rijs as spiritual flaws. ↩︎

  6. This purification, in contrast to the divinely guaranteed infallibility granted to the Ahl al-Bayt (a.s.) through God’s creational will, represents the Qur’anic principle of spiritual refinement through personal effort and adherence to divine commandments. Verses such as ‘God does not desire to put you to hardship, but He desires to purify you and to complete His blessing upon you so that you may give thanks.’ (), ‘Take charity from their wealth to cleanse them and purify them’ (), and ‘Successful indeed is the one who purifies it, and unsuccessful is the one who corrupts it’ () emphasize that individuals attain purity through repentance, acts of worship, and striving against the self to achieve moral and spiritual excellence.” ↩︎

  7. The Verse of Purification is embedded within verses addressing the Prophet’s wives, but narrations confirm its independent revelation. This pattern of inclusion mirrors other Qur’anic verses, where distinct revelations are placed within broader contexts for thematic continuity. Reference: Al-Suyūṭī in al-Durr al-Manthūr cites narrations supporting the independent nature of the purification clause. Such embedded sentences are also termed as “parenthetical sentences” in exegesis. ↩︎
